Embodiment 1

[0049] Picture 1-1 It is a schematic diagram of the first implementation flow of the image processing method of the embodiment of the present invention, such as Picture 1-1 As shown, the image processing method can be applied to electronic equipment, and the method includes:

[0050] Step S101: acquiring the current frame image of the target object;

[0051] Wherein, the current frame image of the target object may be an image saved in its own storage unit before the electronic device performs a photographing action / shutter. Specifically, the electronic device may directly acquire the current frame image of the target object from its own storage unit by way of preview.

[0052] Here, the electronic device may be a mobile phone, a PC, a tablet computer, a personal digital assistant, and the like.

[0053] It should be noted that in practical applications, as the resolution of electronic devices is getting higher and higher, the preview frame rate of sensors with 8M or 16M re...

Embodiment 2

[0078] figure 2 It is a schematic diagram of the implementation process of the image processing method in the embodiment of the present invention Figure II ,Such as figure 2 As shown, the image processing method can be applied to electronic equipment, and the method includes:

[0079] Step S201: acquiring the current frame image of the target object;

[0080] Step S202: Perform a histogram analysis on the current frame image to detect whether the dynamic range of the current frame image meets a preset condition;

[0081] Specifically, the electronic device detects whether the dynamic range of the current frame image meets the preset condition by performing histogram analysis on the current frame image; If the exposure area exceeds the preset ratio threshold, it is determined that the current frame image does not meet the preset dynamic range condition, and the subsequent step S203 is executed.

[0082] Step S203: When there is an exposure area in the current frame image...

Embodiment 3

[0094] image 3 It is a schematic diagram of the implementation process of the image processing method in the embodiment of the present invention Figure three ,Such as image 3 As shown, the image processing method can be applied to electronic equipment, and the method includes:

[0095] Step S301: acquiring the current frame image of the target object;

[0096] Step S302: performing partition brightness analysis on the current frame image to detect whether the dynamic range of the current frame image meets a preset condition;

[0097] Specifically, the electronic device detects whether the dynamic range of the current frame image meets a preset condition by performing a partition brightness analysis on the current frame image; when the average brightness of at least one partition in the current frame image exceeds the preset If the brightness threshold is set, it is determined that the current frame image does not meet the preset dynamic range condition, and the subsequent ...

Abstract

The invention discloses an image processing method and electronic equipment. The image processing method comprises the following steps: detecting a dynamic range of a current frame image after obtaining the current frame image of a target object by the electronic equipment; determining an image compensation direction according to the dynamic range of the current frame image; further adjusting an original exposure parameter according to the determined image compensation direction so as to obtain an adjusted exposure parameter; acquiring the image of the target object by utilizing the adjusted exposure parameter so as to obtain a new frame image; and synthesizing the new frame image and the obtained current frame image so as to obtain a high dynamic range image of the target object.

Description

technical field [0001] The invention relates to data processing technology, in particular to an image processing method and electronic equipment. Background technique [0002] At present, in the case of multi-frame exposure, it is generally necessary to collect 2-3 images with different exposure parameters to synthesize a high dynamic range image (HighDynamicRange, HDR). In this way, the time for collecting 2-3 frames of images with different exposure parameters belongs to the waiting time, and each frame usually takes 30-200ms, which will occupy about 1 / 3 of the entire HDR image generation time, thus seriously affecting the entire HDR image generation rate. , reducing user experience. Contents of the invention [0003] In view of this, the embodiments of the present invention provide an image processing method and an electronic device to solve the problems existing in the prior art. [0004] The technical scheme of the embodiment of the present invention is realized lik...
